Exhaust cat sensor question

So I can see I have the 02 sensor on the down pipe and there seems to be another sensor that goes into my cat which I have never seen before on a Honda.if I remove this,am guessing it will throw a code? And does it require that sensor to be there?

I am wanting to decat my car that's why am asking

2nd sensor on a 4th gen can be unpluged, it's a heat monitoring sensor for the cat. Cut the wire and Earth it to ground. No light and no issues.

I'm guessing this works on a 5G, too (?)

dont think 5G cats have this (overheat) second sensor
